The invention discloses a stroke foundation Chinese font small character quality display method and device. When Chinese font expressed in high resolution space is filled into lattice font image in low resolution, the problems that quality variation is produced and the image is unacceptable can not be avoided. The scheme provided by the invention is based on: Chinese font expressed by stroke foundation font data is adopted; the Chinese font is distributed on a lattice coordinate system; and the stroke shape of combined font is converted to generate new font; the new font is filled to generatea low resolution lattice font image with Chinese small character quality; wherein stroke shape converting on lattice space is judged according to sample of the stroke shape covered on a lattice pixeland covering value, the stroke shape converting includes that the sample information of the stroke covered on the lattice pixel is changed according to a key point for moving the stroke and width value for reducing the stroke, so as to avoid crowd between strokes and increase blank pixels between stokes, thus achieving the requirement of small character quality.
